Posting Code

  • Use Markdown, and it will escape the code for you, like `<div class="cool">`.
  • Use triple-backticks for blocks of code.
      <h1>multi-line block of code</h1>
      <span>be cool yo.</span>
  • Otherwise, escape your code, like <code>&lt;div class="cool"&gt;</code>. Markdown is just easier though.
